EEPORT OP liTATIONAL MUSEUM, 1925 95 



is such an important part of the railway industry that it should be 

 included, if only in a general way, in the transportation section of 

 the Museum. 



In the section of aeronautics a number of photographs of dis- 

 tinctive types of aircraft, both heavier-than-air and lighter-than-air, 

 were received as transfers from the War and Navy Departments and 

 as gifts from the Goodyear Tire and Rubber Co., Akron, Ohio. 

 James V. Martin, Garden City, Long Island, N. Y., a noted pioneer 

 in aviation, presented the original K-III airplane designed by him 

 in 191T for combat service. This embodies a retractable landing 

 gear and K-strut wing fittings, both of which are features patented 

 by him. This plane is unusual in its low horsepower and small 

 size, its wing spread being about 20 feet. It is propelled by ^, two- 

 cylinder Gnat engine. 



In the electrical engineering section the Edison Lamp Works of 

 the General Electric Co., Harrison, N. J., presented three new types 

 of electric lamps for addition to the series of incandescent lamps 

 which the company began in 1898, These represent the largest and 

 the smallest incandescent electric lamps made. The two large lamps 

 have a capacity of 30,000 and 10,000 watts, respectively. Their 

 particular use is in searchlights and in places where an approach 

 to the intensity of sunlight is desired, as in photographic work. The 

 third specimen is of the size of a grain of wheat and is used in 

 surgical work, particularly for illuminating the stomach, the lamp 

 being swallowed temporarily by the patient. D. McFarlan Moore, 

 inventor and noted pioneer in electric illumination, added to his col- 

 lection of experimental electrical apparatus a type of incandescent 

 electric lamp designated as a negative glow lamp. This type was 

 invented by him approximately 30 years ago, but only recently was 

 real use found for it in connection with radio movies. 



Textiles, medicine, wood technology, organic chemistry, and food. — 

 The most valuable additions to the textile collections this year were 

 the gifts received from cooperators of former years, American manu- 

 facturers who had previously sent the Museum many fine examples 

 of the textile industry. In this connection should be named Cheney 

 Bros., South Manchester, Conn., who contributed 50 specimens of 

 silk dress, millinery, drapery, and upholstery fabrics, comprising 

 tinsel goods, printed silks, chiffon velvets, and cut velvets. These 

 specimens were specially selected for the National Museum, and the 

 dress materials and millinery velvets were installed in a large case 

 at the foot of the main aisle in the South Hall by an expert deco- 

 rator who had just returned from Paris, where he had set up in the 

 Louvre an exhibit of American silks manufactured by this same 

 firm.
